I tried herdr recently, and I missed many tmux features I really liked.

tmux has a better `prefix-[` mode where you 1) can do visual selection using line/block mode 2) you can use `o` to switch to other side (just like vim) 3) it pauses/freezes the state of the output so you have time to capture

In herdr, its very basic and incomplete if you're a vim/nvim/tmux power user. And if you're in a TUI that shows some text and then hides it, its hard to do the selection in herdr before it disappears.

To give herdr credit, I did like it's `prefix-e` which opens the history in vim so you can you real selection utils.

As I was looking at herdr, I found there many other solutions that were like it built on the more robust tmux. I am still evaluating, but there are plenty of solutions that have hooks to observe what's going on in agents in other panes/windows like herdr.

I like the Primeagen's `tmux sessionizer` style solutions for nvim to work with git worktrees that each agent may be in. And I like the tmux-agent-sidebar.

I was pretty excited to come across this over the weekend.

In my first year of engineering (UBC), some 2nd years advised me to get an HP48 calculator. It was expensive, but worth the investment they said. I bought the 48GX, a 128KB memory card and some books... and glad I did. This calculator has served me well... but today some of the keys don't work as well as they used to. And I can't get a suitable replacement. I have and use an emulator on my phone and desktop - but its not the same. And the newer HP calculator keys don't feel great to me. In the meantime, I rely on the more reliable vintage HP15c (one built in the 80s with silicon on saphire and amazing keys).

I really appreciate SwissMicros building high quality clones of the best HP calculators. And I am super excited about what the hint of upcoming products based on Saturn Emulation. That must mean a DM48 is on the horizon!

I have a child starting kindergarten. 1/2 the class is attending in person M and Tu and the other 1/2 is via a chrome book and Google Meet. Wed all kids are attending via Google Meet (the classroom will be deep cleaned Wed). And then Th/Fr is like M/T, but the group that was in person is now at home and vice versa. Then they deep clean again on the weekend. (Their day is 6 hrs (less recess and lunch)).

Not only is it going to be challenging for the kindergarten kids to stay focused on their class via chrome book, the SAME teacher is managing the kids in the classroom and the kids online. The kindergarten teachers each have an assistant too (as they did before Covid-19) so that helps a bit.

I am fortunate my wife stays at home with the kids. I can't imagine what it will be like for parents of kindergartners who both work, or parents with special needs kids or parents who don't speak English. I am supportive of social distancing in these times. But its going to be tough on the kids.

"The raw energy density of liquid ammonia is 11.5 MJ/L,[64] which is about a third that of diesel."

https://en.wikipedia.org/wiki/Ammonia#As_a_fuel

(Note this is energy density by volume, which is the metric most care about. Energy density by weight of H2 gas is great, but the volume is enormous in comparison.)

https://en.wikipedia.org/wiki/Hydrogen_storage

Ammonia has been long recognized as a great medium for energy storage and you can generate at the site of electric generation. But the challenge has been extracting the hydrogen from the ammonia. My understanding is that hydrogen crackers exist, but have only been successful commercially at large scale. A portable cracker that you can put on a car that extracts hydrogen on demand from an ammonia storage tank is the innovation we need to see. Apparently there is work in Denmark that looks promising... (And now there is this new membrane technology from Australia.)

Personally, I am cheering for ammonia as a storage means. I am not a fan of batteries found in today's electric vehicles because there are too many conflict minerals in them. Maybe Tesla will succeed mining colbat in Colbat Ontario Canada... But until then, it is probably coming from the Congo or Bolivia.

In addition to the efficiency concerns, France should be thinking about the conflict minerals that are likely in these solar panels. I am supportive of efforts to reduce energy consumption and alternative more environmentally friendly energy sources. And it's exciting to hear about new solutions for energy that appear affordable. But I am hesitant to use technologies that use conflict minerals. Before we make decisions about buying innovative products like solar cells, we need greater awareness about the materials they use and where they are coming from.

Thanks - I never noticed the difference.

I am a proud Canadian who lives in the USA and have a little Canadian sticker on my car. It's my little shout out to other Canadians on the road. I guess we're quietly showing our pride to others. Being loud about it is not in our nature. But I do like that luge helmet :)
